EPA Moves to Force Engine Makers to Fix Notoriously Faulty Diesel DEF Systems, Citing Major Savings for Farmers

[testerdahl]

The U.S. Environmental Protection Agency is ramping up its pressure on engine makers to fix persistent persistent diesel exhaust fluid (DEF) system failures that have disrupted farming, trucking, and heavy-equipment operations nationwide. They are demanding detailed data from manufacturers while advancing fixes it says could save family farms millions of dollars annually. Faulty Diesel DEF Systems Cause Millions In Losses Sudden engine derates and shutdowns linked to DEF malfunctions continue to pose safety risks and productivity losses, according to the agency. EPA Administrator Lee Zeldin said the issue has been a consistent complaint during his first year in office. “As […] (read full article...)

I’m more curious about the data itself than the rest. Hopefully they will make it public.

I suspect the trend will show failures were more common on the older stuff than the newer partly due to improvements and partly due to older trucks having more miles. I don't see how they can reach the 2027 targets without DEF. Maybe they can. Just a wait and see.

It'll be interesting to see how it ends up.

I'm hoping we will see a curve pointing towards more reliability, but diesel engine is the one area where it seems the reliability actually went down.

Everybody I knew had Diesel engines in the 90s and 2000s and drove them till the body would literally fall off from the rust.
Now, nobody wants to touch them with a 100 foot pole and I don't blame them.
